The article presents the results of research which aim was to to determine the impact of local nontraditional fodder additives (zeolite-hongurine of Honguruu deposit, Suntarsky district, and by 1.03% and 3.17%, protein by 0.01% and 0.29%, fat by 0.21% and 0.43%, fibre by 0.10% and 2.29% and nitrogen-free extractive substances by 1.98% and 4.36%, respectively. Animals consuming non-traditional feed additives surpassed their peers from the control group by nitrogen assimilation by 0.23% and 3.10%, calcium by 1.80% and 3.12%, and phosphorus by 0.20% and 5.04%. Thus, unconventional feed additives in cattle feeding contribute to better digestion and assimilation of minerals.
